Question

A third friend wants to offer Rebecca andSteve some of the animal models she hasalready made. The model she has of thegiant squid is 5 inches tall. Using thesame scale (2 in:5ft), how tall would thegiant squid be in real life?

Answer 1

From the present question, it is said that the scale of a model is equal to:

`e=(2in)/(5ft)`

It means that the ratio of the size of the model and the real size of the giant squid must be always this same value. It was given that the size of the model is 5 in. Because we don't know the size of the real-life giant squid, we will use it as x. From this, we can write the following relation:

`(5in)/(x)=(2in)/(5ft)`

Now, we just need to isolate x in the present relation to find how tall would be a giant squid in real life.

`\begin{gathered} \to2in* x=5in*5ft \\ x=(5in*5ft)/(2in)=(25)/(2)ft=12.5ft \end{gathered}`

From the solution developed above, we conclude that the real-life giant squid would be 12.5 ft tall.
